For emphases, I want to reiterate that all therapists are licensed. Go to your state's licensing board. My state has a website where you can check the credentials of doctors and therapists.
As for records, I think they should keep good records. But, I suspect that minimum requirements (laws) don't require good record keeping. Good record keeping is something done to help one to do their job and protect themselves in a law suit.
Some states do allow taping of conversations as long as one party knows. However, some states don't. In therapy, one shouldn't tape unless the client has okeyed it. I wonder if it was in some of the paperwork that you signed initially. I try to read those. But, I wish they would give me a copy for my records. I tend to not be functioning well when I do the paperwork. So I think they should hand me a copy of it. I think it should have also been in your file. There is a reason that it is called "Your file." I suspect you own it unlilke your credit report which is owned by the credit reporting agency. I could be wrong though.
I hope that you report this to your state's licensing agency. His/her actions need to be looked into.
